Application led February 27, 1918.; ialld. 219,450. i

Be it known that I, AL C. KLEM/mja United Statesb. residing at Davenport, in the county/ef/Sc'ott and State of Iowa, have invented/certain new and useful Improvements in Automobile-Hoists, of which the following is a specification.

5 /fThis invention relates to hoists, and more particularly to a hoist especially adapted for lifting automobiles and similar vehicles.

Oneof the main objects ofthe invention is to provide a hoist of the character stated of strong and improved construction, the primary object of thisl invention being to improve the hoist disclosed in my U. S. Patent #1,233,793, granted to me on the 17th day of July, 1917. further object is .to provide a hoist, lthe lifting members of which are ofvery strong construction so as to support the loadbeing lifted, these members being so formed as to be readily produced at small cost. A further object is to provide a hoist in which the blocks for supporting the vehicle axle :may be adjusted longitudinally of the. lifting members so as to vary the leverage exerted by the members in `accordance with` the particular vehicle being lifted. A further object is to provide means for connecting the elements ofthe lifting members or beam so as to effectually prevent any looseness or play between the same While reducing friction to a minimum. Further objects will appear from lthe detailed description.v

taken substantially on devised a hoist in which the i are formed of I-beams slidably mounted on "provided with a bracket `the forward face thereof yond each side of the standard, each end of apertured to receive i/Ii/the form o-f hoist illustrated in my patent above referred to, I have found that it is impracticallto employ the outer sleeve or casing in conjunction with the I-beam to form the lifting member suiiciently strong without making this member unnecessarily heavy and cumbersome. In addition, there is unnecessary play between the beam and sleeve, as well as considerable friction between these members which result in wearing or cuttingv away from the inner surface of the sleeve. This results in the sleeve becoming very loose on the beam so that there is a tendency of these two members to bend or buckle relative to eachother when lifting a heavy load. To avoid this object, I have lifting members each other and provided with means for preventing looseness or play between the same, and also having anti-friction members for reducing friction to a minimum. I have 1 also employed uprights or standards of a new construction from that illustrated in my patent which are so madeas to be relatively light, but sufficiently strong to withstand the strains to which they are subjected. j The base frame of the hoist is provided with the base-beams l and 2 which are of channel construction, the Vforward ends of which are connected by a front angle brace bar 3. Standards f and 5 of I-beam construction are rigidly secured at their lower ends to the forward ends of the basebeams l and 2. These standards are so mounted that the webs thereof are disposed in a parallel relation with the base beams, the channels of the standards being directed laterally of the frame. Each standard is plate 6 secured to and projecting bethis bracket plate being the upper endof one of the braces 7 which are secured to the base-beams, these brace rods serving to efl'ectually eliminate all possibility of looseness or play of the standard. A housingS is fixedly secured to the `inner -end of each base-beam, and these housings rotatably support a shaft 9 disposed transversely of the frame .at the inner end thereof. Suitable rollers l0 are secured `on this shaft within` the 4housings land coperate with caster-rollers l1 adjacent each of the standards, to support the frame so as to permit it to be easily moved from one place to vbase flange 21 of the beam 15.

another. The frame thus produced is of rel- V v Aaiiyely light, but rigid and strong constructinand may be readily transported toV any position desired.

An I-beam 12j is pivotally secured at its inner end to the `inner end of the base beam 1 .by means of a piyot pin 13 which is inserted through the housing 8, the side flanges of base-beam 1 and the web 14 of the beam 12. This pivot pin is positioned closely adjacent the inner end of the beam, andthe base flange of the beam is cut away so as to permit ready movement of this beam about the pin. A similar beam 12a is similarly secured in channel beam 2 by means of a pin 13a. The beams 1-2 and 12a are of' such length as to fit snugly within the' channel .base beams when in lowered position, .the base flanges of these beams corresponding in width toV the interior width'of the channel beams. An I-beam 15 is slidably mounted on the upper face of beam -12 for movement longitudinally of the same.` ThisI-beam is provided at its inner ,end withI a housing 16 which is rigidly secured Vto theV beam. The lower edge portion of v each side wall of this housing is turned inward at right angles to provide a guide flange 17, and these flanges are adapted to engage snugly under the edge portions of the top flange 18 of theLbeam so as to positively prevent movement of the inner end of beam 15 away from beam 12. An anti-friction roller 19 is mounted within thehousing 16 'in rear of the innervend of beam 15. 'This roller corresponds in length to the'width of top flange 18 of beam 12,

andis of such diameter as to bear against the'upperl face of this flange, the roller and flanges `17 coperating to eifectually prevent all looseness or play between vthe -two beams and the roller providing an antifriction mounting for the inner end of beam 15. A bracket 20'is rigidly secured to the web 14 of beam 12 ateach side, and ad jacent the forward end thereof. These brackets eXtend outwardly and upwardly about the top flange 1S of beam 12, and the Each bracket 20 carries, at its upper'end, an antifriction bearing roller 22 which is operative in the channel of beam 15, this roller being iin engagement with the upper face of base flange 21 of the beam. Beam 15 is further provided, at its forward end, with' outwardly and forwardly directed bracket arms 23 rigidly secured to the web 24 of the beam, these' arms projecting about the inner flange 25 of standard 47 and being each provided with an anti-friction roller 26. These rollers correspond in diameter to the distance between the inner flange 25 and Vthe outer iange 27, of the standard 4, and engage snugly into the channels formed in the lateral faces of this 'standard 5 0 as to l15 is mounted on beam 12a and connected' to standard 5 in thesame manneras beam 15 is mounted and connected to its standard.

VA pair of opposed substantially L-shaped A brackets is secured to each ofthe standards at the u ier end thereof, these brackets' providing for1s28 which rotatably support the grooved pulley 'which 29.` y An angle brace bar 30 is secured atitnd to these-A soV forks and serves to maintain the*sangreV in proper spaced relation, this brace barflso-\ i A v V serving to prevent relativefinovement `beV tween the standards at the"` .upper .ends

thereof. LA cable 31 is passed over each pulley 29 and has its free end secured to the Aforward end vof the upper I-beam of.,

the lifting members. These cables 'are secured to drums 32 so as `to-be windable thereon, vthese drums being secured Vto a shaft 331 which is rotatably supported in bearing blocks 34 secured tothestandardsl A worm gear 35 is secured fon oneendfof the shaft and meshes Awith a worm 3-6ro tatably supported in a casing 37 carried by the bearing block 34 mounted Onstandard 4, this worm being rotated bya suitable vcrank 38.

`W'hen'the 'shaft 33 is rotatedV A so as to wind the cables Y31 onto theirv drurns 32, the forward end of I-beams 15 vand 15a will be raised simultaneouslyv on the` standards 4 and 5, the upper I-beamsof the lifting members sliding longitudinally of the lower I-beams so as tofeXtend these members simultaneously with vertical move- A ment thereof'. During, this movement be-V tweenv the I-beams ofthe lifting members,`

these members will be'guided by the anti-'- friction rollers previously referred to so as to preventall Vlooseness or play `while :reducing `the friction to a minimum. As the lifting members are pivoted at their inner or lower ends, comparatively great leverage is exerted thereby during the lifting operation, thus permitting an automobile of comparatively great weight to be lifted or tilted with comparative ease into such position as to permit ready access to the underneath of the same.V

j Itv will be evident that, 'by securing the 4axle of a vehicle to the upper I-'beams of the lifting members, the vehicle may be. readily lifted or tilted by rotating shaft 33 in proper direction for lifting the forward ends `of.

the beams 15 and 15a. For this purpose, an

aXle receivinflV and-supporting block 40 'is f mounted on Thisblock is provided -at veach end with downwardly and, inwardly directed guide arms 41 0f 'substantially' rectangular the upper flange of Veach beam'.

which engage about and under the` edge pori preventing all looseness or play of the block. i A chain 42 is secured at its inner end to the topflange ofk each of the upper :[-beamsA and, at its forward end, to -an eye or ring which is secured to the outer ends of the beam and about which the free end portion of cable 3l is passed and secured by means of a cliplN in the usual manner. The links of this chain are adapted to receive the bill of a hook 43 carried by the shank of a securing hook 44 so as to permit this `securing hook to be ad justed longitudinally of the chain. Securing hook 44 is directed inwardly toward block and is adapted to engage about the axle of a vehicle so as to retain the same on the block. In practice, the automobile is moved into such position as to bring the front axle thereof above the blocks 40, the lifting members being raised slightly so as to bring these blocks into engagement with the under surface of the axle. The hooks 44 are then engaged about the axle thus serving to retain the same on the blocks. By rotating `shaft 33, the lifting members are extended and raised thus liftinof the front axle and the forward portion of the automobile and tilting the vehicle into such position as to permit ready access to the underneath thereof. Blocks 40, while slidable .on the beams 15 and 15, lit comparatively tightly thereon so as not to be readily moved so tliatyduring the lifting operation, this fric- Vtional engagement between the blocks and the beam, combined with the weight of the vehicle, will elfectually prevent movement of the blocks longitudinally of the beams l5 and l5a during the lifting operation, the axle of the vehicle being positively secured against movement by the hooks 44. By having the blocks 40 and the hooks 44 adjustable longitudinally of the lifting members, tlie'leverage exerted by the members may be greatly increased or diminished to accommodate heavy vehicles, and according to whether it is desired to lift the vehicle a slight distance only, or a comparatively great distance. This adjustment of the hooks is readily effected by disengaging hook 43 from chain 42, and sliding the block 40 longitudinally of its supporting beam. When the vehicle has been tilted or lifted, it will, under ordi- -nary conditions, be held in this position by the winding mechanism of unnecessary strain, suitable stop members or pins may beinserted through the web portions of the standards 4 and 5 so as to form stop members for positively limiting downward movement of the guide rollers provided at the forward end of the beams l5 and 15a. For this purpose, I provide each of the standards withV a plurality of perforations extending through the web portion thereof,

` these perforations being disposed in vertical series and at the transverse center of the web. By `lifting the vehicle to the desired lfeight, then inserting suitable stop pins through the webs ,ofthe standards andV lowering the lifting members slightly so as to bring `the guide rollers into engagement with these pins downward movement of these lifting members is positively prevented, and the cables and winding mechanism are thus relieved of all strain.

In the event that it is desired to lift the vehicle into a more upright position than is possible with the lifting members, a supplemental lifting frame designated generally by 46 may be employed. This frame is of substantially triangular outline'and of angle iron construction. An angle-iron brace bar 47 extends across frame 46 remote from the apex thereof, and serves to maintain the arms of the frame in proper spaced relation. This angle bar is adapted to engage over the angle-bar 30 thus rockably supporting frame 46 thereon. A clevis 48 is provided at the apex of frame 46 and is adapted to receive a suitable securing medium by means of whichthe clevis may be secured to the front axle of the vehicle for lifting the same. A

has been raised into extreme position by the lifting means, after which the outer end of frame 46 isdepressed so as to elevate the vehicle, the hooks at the lower ends of rods 49 being engaged into bolts 50, the rods and the frame thus co-acting to maintain the vehicle in lifted position. This supplemental franie, of course, may also be used as an additional securing means for the vehicle when it has been elevated so as to eliminate all danger of dropping of the vehicle in the event of breakage of the cables 31.
